Homeless five‑year‑old Dora survives in a public‑toilet supply closet, making clay figurines of her unknown parents. After her parrot Pip dies, she accidentally discovers her late mother’s magic blue backpack, which can bring newly‑deceased beings back using real memories, physical relics and portraits. Together with Pip and her new friends, she rescues animals and even grants a firefighter seven‑day temporary return to say goodbye to his daughter. When greedy businessmen forge fake backpacks to sell fake resurrection services, Dora firmly opposes turning grief into profit. Step by step, she unravels her own tragic childhood story. She learns about her mother’s death and her amnesiac birth father. In the end, Dora understands the true meaning of farewell and memory, gains two warm families, and no longer needs clay dolls to build her home.
